Witness Inventor without departing CIGERO Er. LA CRGIX, OF BANNIS'I'ER,

mix-mam Specification of Letters Patent.

To all whom it may concern:

Be it known that I, Cronno H. Li Cnorx, a citizen of the United States, residing at Bannister, in the county of San Augustine and State of Texas, have invented a new and useful Wagon, of which the following is a specification.

The object of the invention-is to provide a vehicle of a convertible type consisting of a plurality of members or elements which when used together can be employed in the transportation of long logs or timbers, and whichwhen not required for this purpose can be disconnected and used independently as trucks for hauling other objects or shorter logs, and which when used together may be caused to track, the log supporting means being so constructed and mounted as to avoid cramping or twisting, and prevent nudue strains upon the parts of the vehicle.

Further objects and advantages of the invention will appear in the course of the following description, it being understood that changes in the form, preparation and details of construction may be resorted to within the scope of the appended claim,

from the spirit of the invention.

In the drawings Figure 1 is a side view of a convertible vehicle constructed in accordance with the invention. Fig. 2 is a plan view of the same showing the elements in the positions which they assume in rounding a curve or turning a corner. Fig. 3 s a rear view of one of the trucks. Fig. 4: IS a detail sectional view to show the mounting of the bunks. Fig. 5 is a detail v w in perspective of the coupling forming the corn nection joint.

The convertible vehicle embodying the invention consists essentially of rorward truck 10 and a rearward truck tively having or rigid rea axles i2 and 13 and pivotal front axles 1% and 15, with a jointed connection 16 between said trucks consisting of members 17 and 18, of

substantially equal lengths measured from the vertical planes of the rear axle of the front truck and the front axle of the rear truck and being pivotally united at 19, whereby in rounding a curve or turning a corner the forward end of the rear truck is led through the connection in a direction causing the wheels of the rear truck to track those of the front truck. p

her 17 of the jointed connection is formed as an extension-of the usual reach 20 of the forward truck while the member 18 consists of a short tongue mounted in the usual way in the front hounds 21 of the rear truck. The coupling between the members of the connection should be of such construction as to permit of the relative lateral swinging movement of said members and at the same time permit a limited vertical relative movement thereof, and to this end may consist as shown of a clevis 22 on one of the members carrying the removable pivot bolt hereinbefore referred to as 19 and HHLKQYB carried by the other member and engaged with said pivot bolt, the interval be tween the arms of the to permit theindicated vertical movement of one member relatively to the other to provide for differences in wheels due to unevennesses of the surface of the ground. The forward truck is provided in connection with its front axle with the usual hounds 24c and draft tongue 25. Also mounted in the usual way in reference to both trucks are the front rocking bolsters 26 and rear bolsters 27 and connecting the front and rear bolsters and holding those of each truck in relatively fixed positions are tables 28 and 29, I prising a central or rest timber 3031 and side guide timber 3238, to support the forward and rear pivotal hunks i l-35. These bunks may be of the ordinary and well known construction having the termi nal choclrs 36 and being removably pivoted as at 3? and 38 respectively upon said tables.

As illustrated in Fig. 2', and hereinbefore mentioned, the turning of the forward truck serves to lead the rearward of the curve through the agency of the connection between the trucks and at the same time the bunks of the forward and rear trucks permitted to retain their parallelism held, by the load consisting of long timbers logs supported attheir ends re the level of the truck each preferably corntruck outwardly clevis being such as spectively by said hunks, so that the trucks ed in a slot 39 disposed longitudinally of each truck is removably secured in place by the table and held normally at the forward means oi bolts 41 or similar fastening deend of said slot by means of a spring &0 or vices, wagon bodies of any preferred form its equivalent. Therefore as the trucks are or construction can be substituted therefor. 15 deflected in rounding a curve or corner, the Having thus described the invention, what bunks retain not only their parallelism but is claiined is:

their distance, the rearward bunk being A vehicle having a plurality of trucks pushed backward relatively to the truck in; provided with pivotal front axles, and an opposition to the tension of said spring, and intermediately jointed connection between W hence there is no disturbance whatsoever of the rear axle of the forward truck and the the load and strain upon the vehicle is mini- 1 front axle of the rearward truck, tables supmized. As the trucks resume their normal' ported respectively by the front and rear or straight position, the rear bunk is rebolsters of said trucks, bunks pivotally turned by the spring to its normal position mounted respectively upon said tables, the 1 relatively to the truck. pivot of one of said bunks being mounted With a construction Such as described, in a longitudinal slot in its table, and yieldthe longest timbers can be hauled readily ing means for maintaining the pivot of said and, when the vehicle is not required for last mentioned bunk invits normal position. that purpose, the trucks may be disconnect- In testimony that I claim the foregoing 20 ed simply by the removal oi the pivot bolt as my own, 1 have hereto afiixed my signa- I 19 and either truck may be used independture in the presenceof two witnesses.
